LTE Standard Module Series
EG25-GL_Hardware_Design 71 / 96
It is recommended to use a passive GNSS antenna when LTE B13 is supported, as the use of active
antenna may generate harmonics which will affect the GNSS performance.
5.5 RF Connector Recommendation
If RF connector is used for antenna connection, it is recommended to use the U.FL-R-SMT connector
provided by Hirose.
